Symphyotrichum novae-angliae is a species of flowering plant in the aster family (Asteraceae) native to central and eastern North America. Commonly known as New England aster, hairy Michaelmas-daisy, or Michaelmas daisy, it is a perennial, herbaceous plant usually between 30 and 120 centimeters tall and 60 to 90 cm wide.
Oclemena is a small genus of North American flowering plants in the tribe Astereae within the family Asteraceae.
Symphyotrichum is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family, Asteraceae, most which were formerly treated within the genus Aster. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster and New York aster.
Astereae is a tribe of plants in the family Asteraceae that includes annuals, biennials, perennials, subshrubs, shrubs, and trees. They are found primarily in temperate regions of the world. Plants within the tribe are present nearly worldwide divided into over 250 genera and more than 3,100 species, making it the second-largest tribe in the family behind Senecioneae.
Eurybia spinulosa, commonly called the Apalachicola aster or pinewoods aster, is a perennial herb in the family Asteraceae. It is native to the south eastern United States, where it is present only in the Florida panhandle. Due to its restricted habitat, which is confined to the Apalachicola river drainage, as well as to ongoing development in these areas, the species is of serious conservation concern. It has been listed as critically imperiled by the Nature Conservancy and endangered by the state of Florida.
Eurybia compacta, commonly known as the slender aster, is an herbaceous perennial native to the eastern United States from New Jersey to Georgia. It is commonly found along the coastal plain in dry sandy soils, especially in pinelands. While it is not considered to be in high danger of extinction, it is of conservation concern and has most likely been extirpated from much of its original range. The slender aster was for a long time considered to be a variety of E. surculosa, but Guy Nesom's recent research within the genus has shown that it is distinct enough to be treated as a species. It has also been shown to be related to E. avita and E. paludosa.
Eurybia conspicua, commonly known as the western showy aster, is a North American species of plants in the family Asteraceae. It is native to western Canada and the western United States.
Canadanthus is a North American monotypic genus of flowering plants in the family Asteraceae. The only species is Canadanthus modestus, commonly known as great northern aster or western bog aster. It is native to most of Canada and to northern parts of the United States.
Herrickia is a former North American genus of flowering plants in the family Asteraceae, native to the western United States. In 2004 it was proposed to revive the genus with species that were included in Aster before molecular studies triggered the splitting of that genus into several distinct genera. However, the status of this genus is disputed with Plants of the World Online (POWO) synonymizing it with Eurybia as of 2023.
Symphyotrichum depauperatum, commonly known as serpentine aster or starved aster, is a rare species in the family Asteraceae adapted to serpentine barrens, an ecosystem with a high concentration of toxic metals in the soil. It has been found in Pennsylvania, Maryland, and on some diabase glades in North Carolina. It grows to 50 centimeters and has white ray florets surrounding a center of yellow disk florets.
Symphyotrichum dumosum is a species of flowering plant of the family Asteraceae commonly known as rice button aster and bushy aster. It is native to much of eastern and central North America, as well as Haiti and Dominican Republic. It is a perennial, herbaceous plant that may reach a height of 1 meter.
Eurybia glauca is a North American species of flowering plants in the family Asteraceae, called the gray aster. It is native to the western United States, primarily in Arizona, New Mexico, Utah, Colorado, and Wyoming, with a few populations in Idaho and Montana.
Eurybia kingii is a North American species of flowering plants in the family Asteraceae, called the King's serpentweed or King's aster. It has been found only in the State of Utah in the western United States.
Eurybia wasatchensis is a North American species of flowering plants in the family Asteraceae, called the Wasatch aster. It has been found only in the state of Utah in the western United States.
Symphyotrichum urophyllum is a species of flowering plant in the family Asteraceae native to eastern North America, commonly known as arrowleaf aster.
Symphyotrichum robynsianum is a species of flowering plant in the family Asteraceae native to northeastern North America. Common names include Robyns's aster, longleaf aster, and long-leaved aster.
Symphyotrichum racemosum is a species of flowering plant native to parts of the United States and introduced in Canada. It is known as smooth white oldfield aster and small white aster. It is a perennial, herbaceous plant in the family Asteraceae. It is a late-summer and fall blooming flower.
Symphyotrichum simmondsii is a species of flowering plant of the family Asteraceae endemic to the southeastern United States. Commonly known as Simmonds' aster, it is a colony-forming herbaceous perennial.
Symphyotrichum potosinum is a species of flowering plant in the family Asteraceae native to Mexico and the U.S. state of Arizona. Commonly known as Santa Rita Mountain aster, it is a perennial, herbaceous plant that may reach heights of 15 to 45 centimeters.
